nit: can you change "message_loop" to a bool and rename it to
"run_loop_until_idle"?

I removed changes to this file from this CL. Will refactor this in a separate
CL.

   ElapsedTimer timer;
   if (action)
     action();
   if (timeout.is_zero())
     timeout = TestTimeouts::action_timeout();
   const TimeDelta spin_delay(TimeDelta::FromMilliseconds(10));
   while (timer.Elapsed() < timeout && (!condition || !condition())) {
     SpinRunLoopWithMaxDelay(spin_delay);
     if (message_loop) {
-      message_loop->RunUntilIdle();
+      RunLoop().RunUntilIdle();
     }
   }
   TimeDelta elapsed = timer.Elapsed();
   // If DCHECK is ever hit, check if |action| is doing something that is
   // taking an unreasonably long time, or if |condition| does not come
   // true quickly enough. Increase |timeout| only if necessary.
   DCHECK(!condition || condition());
   return elapsed;
